Impedance: RF cables can be classified based on their impedance values. Common impedance values include 50 ohms and 75 ohms, with 50 ohms being used for most wireless communication and broadcasting applications, while 75 ohms is commonly used for video and television applications.
Voltage withstand and loss: RF cables can also be classified based on their voltage withstand and signal loss characteristics. Different types of RF cables have different voltage withstand capabilities and signal loss characteristics. For example, RG-6, RG-58, RG-213, etc. are common types of RF cables that have different voltage withstand and loss performance, suitable for different application scenarios.
Shielding method: RF cables can also be classified based on their shielding method. RF cables typically require shielding to reduce the impact of external electromagnetic interference on the signal. Common shielding methods include aluminum foil shielding, braided shielding, and aluminum foil with braided shielding.
Wire count: Flat cables can be classified based on the number of internal wires. These wires are usually arranged side by side and can be single wires, multiple wires, or multi-core (such as twisted pair) wires. The choice of wire count depends on the specific requirements of the application, such as the complexity of signal transmission and bandwidth requirements.
Connector type: RF cables can also be classified based on their connector type. There are various types of RF cable connectors, such as BNC, SMA, N-type, TNC, etc. Different connector types are suitable for different devices and application scenarios.
Frequency range: RF cables can be classified based on the frequency range they support. Different types of RF cables have different frequency response characteristics and can cover different RF frequency bands, such as low frequency, medium frequency, high frequency, ultra-high frequency (UHF), very high frequency (VHF), and microwave frequencies.
